Pseudomonas antartica

Those lipases that have been reported for the polyester synthesis are of mammalian (porcine pancreatic lipase, PPL) or fungal (Candida antartica, CA Candida rugosa, CR Candida cylindracea, CC Aspergillus niger, AN PeniciUium roureforti, PR Rhizopus delemar, RD Rhizomucor miehei, RM) or bacterial origin (Pseudomonas cepacia, PC Pseudomonas Jlourescens, PF Pseudomonas species lipase, PS) and so on. 

The copolymerization of 12-, 13-and 16-membered lactones, divinyl esters of adipic and sebacic acid and a,co-glycols by using Candida antartica and Pseudomonas cepacia lipases yielded copolymers of high molecular weight, in moderate yields (Scheme 11.8). Taken together, these results indicated that ROP and polycondensation can occur simultaneously in a one-pot reaction to yield copolyesters [67].
